Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
大尺寸薄板外壳经数控折弯后易发生翘曲,导致门体闭合不严。我们采用折弯回弹补偿模具+多点定位成型工艺,确保柜体框架平整笔直,门体与柜体间隙均匀性控制在严格范围内。
切割不均匀和装配偏差会导致户外应用出现漏水风险。我们采用激光精密冲裁和焊后打磨工艺,精准匹配定制的硅胶密封槽,确保长期户外安装后仍能保持稳定的IP54/IP65防水等级。
杆夹支架的安装孔容易出现位置偏差,导致现场杆件安装困难。我们采用一次性一体式冲孔夹具,确保孔距一致,无需二次钻孔调整即可快速组装在圆形/方形杆件上。
普通表面处理在长时间的日晒雨淋下容易出现剥落和生锈。我们采用彻底的脱脂、磷化预处理以及均匀的粉末涂层,并加强边缘和焊缝覆盖,从而提供卓越的耐盐雾性能和超过10年的户外使用寿命。
完整的独立生产流程:激光切割、数控折弯、焊接、研磨、攻丝、密封槽加工、粉末涂装,无外包环节,成本控制更佳,交货周期更短,生产过程完全可追溯。
在监控通信行业的户外电气柜设计和生产方面拥有丰富的经验,熟悉 IP 防水结构设计、杆式安装组装结构和内部布线布局,能够提供专业的 DFM 优化建议,以降低您的组装和售后故障率。
对每笔订单进行首件检验、过程尺寸测试、成品防水密封抽样测试,有效避免批量生产中的尺寸波动,为大型安防工程项目提供稳定的长期订单交付。
可定制材质(SPCC、SGCC、不锈钢、铝合金)、外壳尺寸、门结构、立杆安装方式、内部隔板、电缆入口孔、IP防护等级和表面涂层;可提供激光雕刻品牌标志和个性化包装。
